Title: Improvements in synchromesh gears
IPC: F16D23/04
Filed: 1937-03-19
Abstract: 494,411. Positive clutches. HAWORTH, L. March 19, 1937, No. 26668/38. Divided out of 494,338. [Class 80 (ii)] In synchromesh change-gear mechanism, the engagement under the control of the gear lever of a pair of friction elements, prior to the engagement of dog elements, produces a rotation of the slidable friction element relative to its associated slidable dog element whereby, through cam surfaces, an axial thrust is imparted to a second slidable friction element so as to press the latter against the fixed friction element, the reaction to this axial thrust being transmitted to the gear shaft. A double-ended fork-actuated dog sleeve G<1> is splined on a collar G of the gear shaft A. Sleeves G4 and G<6> mounted in the sleeve G<1> on either side of the collar G each carry a friction cone, and sleeves G<5> and G<7> mounted within the sleeves G<4> and G<6> and each carrying a friction cone are splined on the shaft A and are urged towards the collar G by a spring K. Rings J<2> and J<3>, interposed between the sleeves G<5> and G<7> and the collar G, have camshaped ends co-operating through interposed balls J<6> and J<7> with the complementary camshaped ends of the sleeves G<5> and G<7> the rings being coupled for rotation with the sleeves G4 and G<6> by pins J and J<1> projecting from the latter into axial slots in the former. The sleeves G<4> and G<6> carry spring rings H and H<1> normally engaging grooves in the sleeve G<1> and are spaced by pins G<8> slidable in the collar G. If the sleeve G<1> is moved, say, to the right, from the neutral position shown, for engaging it with dogs on the freely-mounted but axially-fixed pinion B<2>, the sleeve G<6> is carried along by the spring ring H<1> and is brought into frictional engagement with the gear B<2>. The consequent rotation of sleeve G6 relative to the shaft is imparted to the ring J<1> and, due to the cam surfaces, the sleeve G<7> is thrust into frictional engagement with the gear B<2>. A dash-pot may be provided to control the movement of sleeve G<1>.

Title: Underply turn down and stitching device for a tyre-building machine
Inventor: MALLORY EDWIN ELLSWORTH
IPC: B29D30/28
Filed: 1950-11-03
Abstract: 687,027. Tyre-building machines. NATIONAL RUBBER MACHINERY CO. Nov. 3, 1950, No. 26953/50. Class 144 (i). In a tyre-building machine, means for holding down the under-ply fabric U on the end portions of the flat surface of the building- drum D whilst the overhanging edge-portions are being folded down the ends of the drum, comprise a power-cylinder 18 pivoted on a fixed support with a pair of pistons which are actuated in succession; first, to move a stitcherroll up to the fabric on the drum and then, at a relatively slower speed, to move a turn-down roll over the edge-portion of the fabric. As shown, pairs of rolls 1, 2 are adjustable on a rock-shaft 3, the rolls 1 being carried on swinging arms 4 on the shaft and the rolls 2 on arms 12 fast on the shaft. When the rolls 1 contact the flat surface of the drum, further rocking of the shaft 3 advances the rolls 2 down the ends of the drum whilst pressure of the rolls 1 is increased by means of springs 9 fitted between lugs 8 on the arms 4 and lugs 6 fast on the shaft. The power-cylinder 18 is divided by a wall 22, the upper portion being fitted with a piston 19, the rod 20 of which is pivoted to a yoke 15 on the shaft 3 and the lower portion with a piston 23 whose rod 24 is pivoted at 25 to the fixed framing 16. In use, the rolls are rocked into initial operative position by actuation of the piston 19 which, at the end of its stroke, uncovers a terminal port in the cylinder-wall to direct a restricted flow of fluid between the partition 22 and piston 23. The assembly of cylinder 18 and piston 19 is thus advanced, at a slower rate, to move the rolls 2 down the ends of the drum.

Patent GB-866392-A (GB)
Title: Process for the production of elastomeric plastics
IPC: C08G18/67
Filed: 1959-08-11
Abstract: In a process for the production of elastomeric plastics by reaction of polyhydroxyl compounds having a molecular weight higher than 800 with an excess of an organic diisocyanate and subsequent incorporation thereinto of an unsaturated glycol in a quantity insufficient for reaction with all the free isocyanate groups of the isocyanatemodified polyhydroxyl compounds, on subsequent reaction with shaping, the diisocyanate is used in an excess of 300 to 700% over the amount necessary to provide a number of isocyanate groups in the reaction mixture equal to the number of hydroxyl groups provided by the polyhydroxyl compound, and a butene-1, 4-diol or butine-1, 4-diol, which may if desired be 1, 4-alkyl-substituted, is used as the unsaturated glycol. Linear polyesters, polyesteramides, polyethers, polythioethers, polyacetals, and linear polymerization products of butadiene or isoprene containing hydroxyl groups are suitable polyhydroxy compounds.  Acid substances, such as hydrochloric acid can be added to the cross-linking component to lengthen the casting time of the reaction mixture.  In Examples 41 a glycol-adipic acid polyester (OH number 56) is reacted with 570% excess of 1, 5-naphthylene diisocvanate.  The product is mixed with butene-1, 4-diol, the melt is poured into moulds preheated to 120 DEG C. and the cast product is heated at 100 DEG C. for 24 hours; (2) a 475% excess of naphthylene diisocyanate is employed in a similar process; (3) a tetrahydrofuron polymer is employed as the polyhydroxy compound; (4) butine-1, 4-diol is employed as the glycol in a process similar to that of (2); (5) and (6) a polythioether (OH number 53) from thiodiglycol and triethylene glycol is employed as the polyhydroxy compound, with 1, 5-naphthylene and 4, 41-diphenyl methane diisocyanates, respectively, and butene-1, 4-diol as the glycol.

[Class 110 (ii)] An apparatus for pumping blood, or other fluid, comprises a flexible tube 29 operated upon by a roller 13 on a crank disc 6 by means of a handle 10. Fig. 1 shows the apparatus with a part 18 slid back from a block 3 to allow the insertion of the tube 29, rings 32, 33, entering grooves 34<1>, 34. A handle 26 is then turned about spindles 25 and causes eccentric pins 48, in slots 49, to move the part 18 along guide pins 16, 17, close to blocks 3 so that curves 22, 21, form a circle around the tube. The two ends of the tube lie in different planes. A hodometer 27 is attached to record the number of revolutions made by the roller 13, through a link 28 and an eccentric 28<1>. The roller 13 may be adjusted with respect to the tube by means of a worm 35 and wormwheel 36, operated by a screw-driver, the bearings of the spindle 12 being eccentric to the spindle. Similarly a worm 51 is used to adjust the bearings of the spindles 25 in order to secure a close fit between block 3 and the part 18. To prevent rotation in a reverse direction, a ball 38 bears against the periphery of the disc 6, when a cam 46 is turned to allow a spring 42 and piston 39 to push the ball 38 as a second piston 40 is retracted. A screwdriver 37 is attached to the pump, and accessories or instruments are contained in a removable bottom.
Patent GB-651681-A (GB)
Title: Continuous centrifugal machines
IPC: B04B3/04
Filed: 1948-10-22
Abstract: 651,681. Centrifugal separators. CLARK, G. M. (Western States) Machine Co.). Oct. 22, 1948, No. 27519. [Class 23] In a strainer separator, particularly for heavy granular material, the material is fed through a rotary basket 10 by reciprocations of a rotary feed screw 20, the screw rotating at substantially the same speed as the material to feed it during strokes of the screw from left to right, and the screw rotating at a different speed to that of the material so as not to move it during return strokes of the screw from right to left. The basket has radial outlets 16 for the material and is supported in bearings by hollow shafts 12, 14. Within the shafts bearings 27, 29 are provided to support the screw shafts 26, 28. Material is fed into the basket by a tube 18 and passages 17 in the screw. The basket and screw are rotated from a shaft 51 by gears 53, 54, and 56, 55. The gear ratios are such that the screw tends to rotate faster than the basket. The gear 56 is linked to the gear 53 by a spring 57 the resilience of which causes the rotational speed of the screw to decrease under the resistance of the material during the feed strokes.and to increase when this resistance is removed during the return strokes. A cylinder 41 is fixed to the screw shaft 26, and houses a piston 42 fixed to the basket shaft 14 so that fluid supplied to the cylinder from a valve 49 causes the screw to reciprocate. In a modification, Fig. 3 (not shown), the cylinder is integral with the discharge end of the basket, and the piston, fixed to the screw shaft, is reciprocated by fluid supplied through passages in the screw shaft. The screw and basket are rotated by belts driven from a common drive shaft. The basket and screw pulleys are respectively fixed and loose on the basket shaft, and the loose pulley co-operates with an axially movable clutch member rotationally fixed to the screw shaft. During the feed stroke the screw is turned by the material in the basket, but during the return stroke the clutch is engaged and the screw is driven faster than the basket. Fluid pumped from a tank is supplied to either side of the piston by means of a rotary timer, switches operated by the screw shaft reciprocations, and solenoid-operated valves. In a further modification, Figs. 4-7 (not shown), the arrangement of piston and cylinder is similar to that described in the first modification, and the rotational drive is by V-belts. The screw and basket pulleys are fixed to their respective shafts, and the rim of the screw pulley is rotationally movable, relative to its hub so that the differential rotation of the screw and basket is obtained in a similar manner to that described with reference to Fig. 1.
